An interactive installation based on the “wobble vision” technique.
Sound picked up by a contact microphone is amplified and used to drive the cathode ray tube of a discarded television. The end result is a pattern on the screen that looks (to me) like ripples in a pond. Manipulating the spring, stomping, or yelling creates “waves” that travel outward.

It’s a fun way of showing off the tiny sounds that are all around us, all the time.

Originally inspired by the idea of a drop of water falling into a pond.
Here are videos of the first tests with Wobble vision and spring.
